Blemished
Blemished is best for visible marks or imperfections that spoil an otherwise smooth appearance.
Example: The polished surface was blemished by a deep scratch.

Erroneous contrasts with flawless when the issue is factual or logical error rather than physical quality.
Example: The article was corrected after an erroneous figure was identified.
Inaccurate
Inaccurate describes information, measurements, or descriptions that are not sufficiently correct.

Incomplete means missing necessary parts or information, so it is a contextual rather than universal opposite of flawless.
